Protocol for obtaining doubled haploids in isolated microspore culture for poorly responsive genotypes of brassicaceae family.

In this protocol for obtaining doubled haploids plants (DH), we propose a new method for microspore isolation. This method is useful for genotypes of the Brassicaceae family with low responsiveness to DH technology. For such crops, it allows increasing the embryo yield several times and sometimes obtaining embryos for the first time.

Identification and Pathogenicity of Species Associated with Onion Basal Rot in the Moscow Region of Russian Federation.

Fusarium basal rot of onions causes large losses during storage of commercial production of onion bulbs, which in turn adversely affects the food market situation in the off-season period. There are no data on the composition of spp., which causes onion basal rot in the Russian Federation.

The Accumulation of Volatile Compounds and the Change in the Morphology of the Leaf Wax Cover Accompanied the "Anti-Aging" Effect in L. Plants Sprayed with 6-Benzylaminopurine.

Essential oils (EOs) are of commercial importance for medicine, food, cosmetics, the perfume industry, and agriculture. In plants, EOs, like the wax cover, serve as protection against abiotic stresses, such as high temperatures and water deficiency. The use of spraying with exogenous hormones of aromatic plants affects the accumulation and composition of volatile compounds, as well as tolerance to abiotic stress.

Mastering DNA Content Estimation by Flow Cytometry as an Efficient Tool for Plant Breeding and Biodiversity Research.

Flow cytometry gives a unique opportunity to analyze thousands of individual cells for multiple parameters in a course of minutes. The most commonly used flow cytometry application in plant biology is estimation of nuclear DNA content. This becomes an indispensable tool in different areas of plant research, including breeding, taxonomy, plant development, evolutionary biology, populational studies and others.

Production of Gynogenic Plants of Red Beet ( L.) in Unpollinated Ovule Culture In Vitro.

The unique and balanced components of the biochemical composition, together with high antioxidant activity, make the red beet necessary a dietary vegetable crop, much contributing to healthy food ration. The application of the technology for producing gynogenic plants in vitro increases the genetic diversity and significantly reduces the period of time required to obtain the appropriate homozygous lines used to create the F1 hybrids that are demanded in the market. For induction of gynogenesis, we used IMB medium developed by us with the addition of 55 g/L sucrose, 3 g/L phytogel, 200 mg/L ampicillin, and 0.

Embryogenesis of European Radish ( L. subsp. Convar. Radicula) in Culture of Isolated Microspores In Vitro.

The European radish is one of the most unresponsive crops in the family to embryogenesis in microspore culture. The aim of this work was to study the process of embryogenesis of European radish and its biological features. In this study, the embryogenesis of European radish is described in detail with illustrative data for the first time.

Androgenesis of Red Cabbage in Isolated Microspore Culture In Vitro.

Red cabbage belongs to the economically important group of vegetable crops of the Brassicaceae family. A unique feature of this vegetable crop that distinguishes it from other members of the family is its unique biochemical composition characterized by high anthocyanin content, which gives it antioxidant properties. The production mainly uses F1 hybrids, which require constant parental lines, requiring 6-7 generations of inbreeding.

Protocol of European Radish (Raphanus sativus L.) Microspore Culture for Doubled Haploid Plant Production.

Here, we describe the first protocol of European radish (Raphanus sativus L. subsp. sativus convar.

Brassica rapa L. ssp. chinensis Isolated Microspore Culture Protocol.

Culture of isolated microspores is a widely used method to obtain haploid and doubled haploid plants for many crop species. This protocol describes the steps necessary to obtain a large number of microspore derived embryos for pakchoi (Brassica rapa L. ssp.

Factors affecting DH plants in vitro production from microspores of European radish.

Over the recent years the market demand for scaling up the production of European radish (Raphanus sativus L.) varieties and hybrids for open and protected production, varying in ripeness group, root shape and color, has drastically increased. Therefore, the expansion of genetic diversity and acceleration of the selection process are important.

Haploid Embryogenesis in Isolated Microspore Culture of Carrots ( L.).

The process of embryogenesis in isolated microspore culture was studied in eight carrot accessions of different origin. The ½NLN-13 medium supplemented with 0.2 mg/L 2,4D and 0.

Effect of Beta-Lactam Antibiotics on Microspore Embryogenesis in Species.

Antibiotics are widely applied for plant cultivation in vitro to eliminate bacterial contamination. However, they can have both positive and negative effects on the cells of cultivated plants, and these effects largely depend on the type antibiotic used and its concentration. The objective of the present study was to estimate the effect of β-lactam antibiotics ampicillin (Amp) and cefotaxime (Cef) on microspore embryogenesis induction in vitro in the species.

Effects of Genotype and Culture Conditions on Microspore Embryogenesis and Plant Regeneration in ssp. L.

Turnip is a biennial crop and, consequently, the creation of pure lines for breeding is a time-consuming process. The production of pure turnip lines using doubled haploids produced in isolated microspore culture has not been sufficiently developed. The aim of the present work was to determine some key factors inducing embryogenesis in the isolated microspore culture of turnip, as well as investigating the manners of embryo development.
